This one's cute: rules for miniatures wargaming using the kinds of toys you'd generally find in a standard toybox. While you can use action figures, the rules are more geared to generic type toys like trains and "100 for a dollar" bagged army men.

The basic rules are simple, without giving much of a nod to balance -- you'll have to use some optional rules if you want things like accurate line-of-sight and sensible point costs. For what they're intended to do, though, they're serviceable, and you can learn them quickly.

This game seems to be intended more as an introduction to wargaming for children (probably 9 and 10 year olds) than as a game for adults. While it's fun, there's not much room for growth. Team Frog makes another game, Critter Commandos, that is similarly kid-friendly but has much more meat (err.. polystyrene) to it.
